Kinematics and mechanics of ground take-off in the starling Sturnis vulgaris and the quail Coturnix coturnix .

Quail (Coturnix coturnix) Science Article 3 abstract The mechanics of avian take-off are central to hypotheses about flight evolution, but have not been quantified in terms of whole-body movements for any species. In this study, I use a combination of high-speed video analysis and force plate recording to measure the kinematics and mechanics of ground […]

Comparison of migratory tendency in European Quail Coturnix c. coturnix, domestic Japanese Quail Coturnix c. japonica and their hybrids

Quail (Coturnix coturnix) Science Article 4 abstract Since the 1970s, the decline of the occidental populations of European Quail Coturnix c. coturnix, a partial migrant Galliform species, has driven the release of domestic Japanese Quail Coturnix c. japonica into the wild as game birds. Recent experiments suggest that reproductive isolating mechanisms have not developed to […]

Fluctuations related to rainfall in richness and abundance of birds of steppic Mediterranean habitats

Quail (Coturnix coturnix) Science Article 6 abstract The existence of interannual variations in the richness and abundance of bird species breeding in pseudo-steppic Mediterranean areas is analysed and related to the important fluctuations that take place in rainfall, which in turn deeply influence vegetation growth. The hypothesis of food limitation as a key factor in […]

Foam produced by maleCcoturnix quail: what is its function?

Quail (Coturnix coturnix) Science Article 2 abstract Males of the Old World quail genus Coturnix are unique among birds in possessing a well-developed proctodeal gland. The gland and associated cloacal musculature are sexually dimorphic, androgen dependent, and produce a foamy substance that is introduced into the female along with semen during copulation, suggesting that the […]
